Sail across the sea

Chapter 54 Is Gao Fan Right?
"I saw a document saying that Pujiang Chemical Research Institute tried adding cerium oxide to the catalyst in the 50s, and found that the activity of the catalyst was better than that of traditional catalysts, but it was not suitable for industrial applications because of its poor strength. It can be promoted, have any uncles and aunts heard of this?"

Gao Fan asked a group of engineers in the technical department.

Everyone was at a loss, this point of knowledge was a little too remote, and everyone had never heard of it.

Gao Fan nodded with satisfaction, and continued: "In the past 20 years, there have been many studies on the catalytic effect of rare earths abroad, but they are mainly used in petroleum cracking and automobile exhaust treatment. It is rare to use rare earths in ammonia synthesis catalysts."

"I know that." Wu Zequn hurriedly opened his mouth. If he didn't speak, he would be despised by this brat. "The catalytic effect of rare earths is mainly because rare earths have a paramagnetic structure, which has a relatively large impact on the hydrogen conversion reaction." Influence, besides..."

"Uncle Wu is right." Gao Fan affirmed, and at the same time interrupted Wu Zequn's eloquence.

A smug smile appeared on Wu Zequn's face, but the smile froze immediately.

Nima, I'm so proud of myself, a brat compliments me, I'm actually proud of it!
"Some studies abroad have shown that various rare earth elements have good catalytic effects. A few years ago, a Swiss company developed a spherical ammonia synthesis catalyst containing 0.5% cerium, which was said to have good low-temperature activity, but because the cost was too high Big, but not promoted." Gao Fan said.

"You mean, you think we can try?" Meng Hai heard the meaning of Gao Fan's words.

Gao Fan just said that there is a new plan, and then he talked about the role of rare earths. Isn't this just trying to develop a rare earth catalyst?Meng Hai couldn't think of the benefits of rare earth catalysts for a while, but people in the chemical industry have the habit of throwing some other elements into the product when there is nothing to do, and throwing a surprise every now and then.

The traditional catalyst is nothing more than ferric oxide, alumina, potassium oxide and calcium oxide, and throwing some cerium oxide into it seems to be no problem.Gao Fan said that someone abroad has already done this, which shows that this method is feasible, at least it will not be worse than the current situation.

Then try it.

"Xiaofan, is this the suggestion you want to make?" Wu Zequn said, "Your basis is because you have seen foreigners do this before?"

"Of course not." Gao Fan said, "The practice of foreign countries just gave me an inspiration. I have thought about this issue specifically, and think that adding cerium to iron-based catalysts should be beneficial.

"First, the effect of cerium oxide is similar to that of potassium oxide, both of which can improve the activity of the catalyst. However, the presence of cerium on the surface of the catalyst will be longer than that of potassium, which can prolong the service life of the catalyst and reduce the frequency of catalyst replacement.

"Secondly, just now Uncle Wu said that rare earth elements have a special magnetic structure, which can effectively improve the low-temperature activity of the catalyst. It has been reported that the reduction temperature of the catalyst can be reduced by more than 40 degrees Celsius after the addition of rare earth elements, which helps Shorten driving time and save driving energy consumption.

"Third, the reaction of cerium with chlorine and sulfur is more active than that of iron. If the raw material gas contains hydrogen sulfide, it will first react with cerium to form sulfide, thus avoiding the sulfur poisoning of the catalyst. Moreover, rare earth sulfide The catalyst is also catalytically active, which makes the catalyst more resistant to toxicity."

Everyone was dumbfounded.

What you said is so reasonable that we can't find a reason to refute it.What is the catalytic activity of rare earth sulfides? This knowledge is beyond the outline. I have never heard of an engineer from a small nitrogen fertilizer factory in a county needing to learn this knowledge.

Someone stole a look at Gao Yiping, and found that Gao Yiping's eyes were also full of horror, which really couldn't be faked.

It is true that Gao Yiping is a college student, but when he became a leader later, his professional skills have long since been abandoned.When it comes to issues such as the production process, Gao Yiping can indeed be regarded as a professional cadre, but when it comes to detailing how the catalyst works, he is definitely not effective.

Even a group of professionals in the technical department can barely understand that this problem is related to principles such as atomic structure and electronic transition. If they ask them to explain clearly, they can't do it.

The things that everyone couldn't do, but Gao Fan said it all, which shows that his knowledge definitely didn't come from the factory, Gao Yiping couldn't teach him, and Zhou Xiaoyun probably couldn't teach him either.Zhou Xiaoyun is indeed very good, but she is not a catalyst, how can she understand these cutting-edge knowledge.

I heard from the children at home that rumors spread in Cangtang No. [-] Middle School that Gao Fan has supernatural powers and has been certified by the Provincial Science and Technology Commission.

I didn't believe it in the past, but now it seems that what I said is true.

"Lao Meng, do you think Gao Fan is right?"

Gao Yiping cheerfully followed his son out to fill up the guns for everyone.He didn't even understand [-]% of what his son said, but he did understand the expressions on everyone's faces, just five words: envy, jealousy and hatred.

I let you speak ill of my son behind his back!

I let you write anonymous letters!

I make you jealous!

Don't even look at who gave birth to this baby!

Do you think my baby is called Gao Fan, so you really think he is ordinary?Let me tell you, on the day Gao Fan was born, I dreamed that an old man with a white beard told me that the future of this son was boundless, and he had to choose a low-key name, so I named him Gao Fan.

You know what a fart!

Looking at Gao Yiping's gloating face, Meng Hai sighed in his heart, forced a smile on his face, and said:

"I think Gao Fan spoke very comprehensively. Many people are now studying rare earths. Some people call it industrial monosodium glutamate. I think we can make a furnace of catalyst by ourselves, add a little of this monosodium glutamate, and try the taste. okay.

"If it is done, our factory will put another satellite. Rare earth catalyst, this is something that even foreigners have not made. Let's make it. This is called glory for the country. Let's talk about it, yes no?"

Could it be?
If you don’t think so, you can tell a lot of truths.

Everyone thought that they didn't have Gao Fan's views, so they could only agree, expressing their opinions in a hurry:
"Yes, you can definitely give it a try!"

"It doesn't matter if you try it, how much will it cost?"

"What Gao Fan proposed, could it be wrong!"

"Tsk tsk, Factory Director Gao, how did you train Gao Fan? Let's pass on the experience sometime, my kid..."

"This has nothing to do with cultivation, it's mainly because the ancestral grave of Director Gao's family is well buried..."
